Question

a certain op-amp has a closed-loop gain of 19 and an upper critical frequency of 30 mhz, the gain-bandwidth product is \boxed{} mhz

Explanation:

Step1: Recall gain-bandwidth formula

Gain-Bandwidth Product = Closed-Loop Gain × Upper Critical Frequency

Step2: Substitute given values

$\text{Gain-Bandwidth Product} = 19 \times 30$

Step3: Calculate the product

$\text{Gain-Bandwidth Product} = 570$

Answer:

570 MHz
